Young iguanodon Aladar is separated from his parents and raised by lemurs on an isolated island. Aladar must discover his heritage just as a meteor crash threatens to destroy his world. Raises the bar on animated adventures by having the impossibly realistic critters superimposed onto actual jungle footage. Pic represents the next step in animation evolution, but the amazing visuals are somewhat undercut by the script, which has a pieced-together feel at times. May be too scary for the wee ones since everything does look so lifelike.
